export images

Dear gang,

How do we get images in the export? Here is my sample (also attached):

==============
\setupbackend[export=yes]

\starttext
\startalignment [middle]
\dontleavehmode
\externalfigure[mill.png]
\stopalignment
\stoptext
==============

div output:

==
<div>
    <div class="image" id="image-1"><!--empty--></div>
</div>
==

So it seems that \externalfigure[mill.png] is tagged in the output but the
image itself is ignored. What am I missing here? pdf output is correct; I
copied mill.png from the context sample folder

/tex/texmf-context/tex/context/sample/mill.png

(png too big to attach here)

Best wishes
Idris

Put mill.png in the images folder which should exist in the export folder.

Thanks, Wolfgang!

One more question on this: How can I setup the images so that I don't have  
to toggle, e.g.

\externalfigure[basmalah.png][width=3in]
% \externalfigure[basmalah.pdf][width=3in]

Is there a way to tell the export to use the png option, while telling the  
pdf output to use the pdf? This is important when the image is made from a  
font (no needs scalability in the pdf). Thanks again, Wolfgang, and

Best wishes
Idris

You can try to use the *export mode to use different images for the XML and PDF output.


The first method is to drop the file extension and tell context to use the PNG files when the export is enabled.

%\setupbackend[export=yes] % uncomment to enable *export mode

\startmode[*export]
  \useexternalfigure[basmalah] [basmalah.png]
\stopmode

% possible but not necessary because ConTeXt prefers images in the PDF format
%
% \startnotmode[*export]
%   \useexternalfigure[basmalah] [basmalah.pdf]
% \stopnotmode

\starttext
\externalfigure[basmalah]
\stoptext


The second method is to specify which image should be used when the export is disabled/enabled.

%\setupbackend[export=yes] % uncomment to enable *export mode

\starttext

\doifmodeelse{*export}
  {\externalfigure[basmalah.png]}
  {\externalfigure[basmalah.pdf]}

\stoptext


The third method is to use two folders for the images in PDF and PNG format.

%\setupbackend[export=yes] % uncomment to enable *export mode

\doifmodeelse[*export]
  {\setupexternalfigures[directory=pngimages]}
  {\setupexternalfigures[directory=pdfimages]}

\starttext
\externalfigure[basmalah]
\stoptext
